Present commercially available full-automatic soybean milk machine, especially adopt the soy bean milk making machine of bottom heating, excessive or heating-up temperature is too high or other reasons when causing sticking with paste the end when food materials in the cup, the part soy bean milk making machine can't stop heating automatically, but continue heating, and then cause at the bottom of the more serious paste phenomenon even security incident to take place; The part soy bean milk making machine is then taked to install temperature controller additional in the bottom, temperature controller disconnects when heating-up temperature has surpassed the critical temperature of temperature controller shutoff, heating tube stops heating, but control module MCU can't detect the phenomenon whether end has taken place to stick with paste, even temperature descends again and when being lower than the critical temperature of temperature controller, temperature controller can not reset automatically, and tends to cause slurrying unsuccessful.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of effectively preventing and sticks with paste end phenomenon, has improved the heater circuit and the control method thereof of the soy bean milk making machine of slurrying efficient.
In order to solve the problems of the technologies described above, the present invention takes following technical scheme:
A kind of heater circuit of soy bean milk making machine, comprise control module MCU, power control circuit, testing circuit and heating tube, power control circuit is connected with MCU by circuit, heating tube is connected in series by circuit and power control circuit, also comprise temperature switch, described testing circuit input end is connected with heating tube one end, output terminal is connected with MCU, and temperature switch and heating tube are connected in series.
The present invention has also disclosed the control method of aforesaid heater circuit, temperature switch automatic cutout when the break-off signal value T1 of the temperature T 〉=setting on the temperature switch, testing circuit detects and sends a cut-off signal to control module MCU after temperature switch disconnects simultaneously, and MCU gives an order and makes power control circuit stop heating work;
Temperature switch is connected automatically when the start-up temperature value T2 of the temperature T＜setting on the temperature switch, and testing circuit detects temperature switch and connects the back and send a connection signal to control module MCU simultaneously, and MCU gives an order and makes power control circuit start heating work.
The break-off signal value is 120 ℃≤T1≤140 ℃, and the start-up temperature value is 110 ℃≤T2＜120 ℃.
The present invention responds to the cup bottom temp in real time by install temperature switch in heater circuit, makes soy bean milk making machine thermal anomaly or heating occur adding when not stopping in heating process, and temperature switch prevents the end problem of sticking with paste according to predefined temperature automatic cutout; When temperature reduced, testing circuit sent signal again and restarts heating for control module MCU, and power control circuit carries out power control, guarantees the slurrying success.
